ROCK PHYSICS AND THE NEOLITHIC AXE TRADE IN GREAT BRITAIN*

This paper is concerned with the products of a number of Neolithic quarries in highland Britain. It investigates the claim that the scale of axe distribution was partly the result of social factors which resulted in these artefacts gaining an added value in areas remote from their sources. One case study considers the sequence of production in Cumbria, in relation to the tensile strength of the rock quarried in different parts of the region. It shows that these considerations had only a limited influence over the choice of stone source and the scale on which it was worked. A second study compares the tensile strength of the main raw materials used for making non-flint axes with the extent to which these sources were actually exploited. Again there is only a limited relationship between the two, suggesting that social factors may indeed have been important.     

RARE EARTH ELEMENT DISTRIBUTION PATTERNS IN SHETLAND STEATITE - CONSEQUENCES FOR ARTIFACT PROVENANCING STUDIES

An attempt has been made to relate steatite artifacts to the source of rock from which they were manufactured, using the distribution patterns of rare earth elements. Radiochemical- and instrumental-neutron activation analyses of Shetland steatites suggest that the use of rare earth elements in artifact provenancing may be unreliable. Concentrations of rare earth elements in many Shetland steatites are too low to be measured reliably by a cost effective method. The relative importance of primary igneous and secondary metasomatic processes in controlling steatite rare earth element geochemistry is discussed and geological arguments against the existence of unique rare earth ‘fingerprints’ for steatite are presented.     

Britische Politiker als Liebhaber der Wissenschaft (ca. 1850–1914) — Zur Ideologie des Amateurismus

The various scholarly and scientific endeavours — comprising both arts and sciences —, which British statesmen persued in their leisure time, transcend the mere biographical aspect. In the light of the slow, yet steady professionalisation of educational and political institutions, many of them modernised or newly created in order to achieve what came to be called “National Efficiency”, the literary and scientific pastimes of men, like Gladstone, Morley, Salisbury, Balfour or Haldane, seemed soon to become somewhat obsolete. Yet, it is argued, that the often professedly amateurish activities did not merely display the traditional hobby attitude to the sciences, so characteristic of the wealthy aristocrat, but in some cases revealed a good understanding of the scientific and educational needs of society, leading up to their active advancement. The British amateurs, it would seem, were pleading for providing a balanced higher education and training, rather than going for the technical excellence of the political rival Imperial Germany, which dazzled and, at the same time, intimidated some of them.     

Integrating Landsat and Land Systems for Cover Maps in Southern Inland Queensland

Digital analysis of Landsat data is applied to up-dating land cover maps for the Goondiwindi district of southern, inland Queensland. The imagery was paired with climax cover maps obtained from land systems reports with analysis conducted separately for each of three climax cover types (open forest, woodland and open woodland). Computer classification using this approach produced readily interpreted and reliable results. This work demonstrates that Landsat can be used in conjunction with existing, land systems derived maps to produce data that combine the advantages of two approaches to environmental survey, the former being based on current land cover/land use and the latter on the original environment and its land use potential.
